One hurdle in finding a spouse is China’s long-standing tradition of hypergamy—or women marrying up, in terms of income and status. The older and more accomplished a Chinese woman is, the narrower her potential dating pool, explains professor Li Yinhe, who researches sex and relationships at the Chinese Academy of Social Sciences (CASS). Even with millions more men than women overall in China—due to rampant abortions of female fetuses by couples hoping for a son—the prospects aren’t necessarily easier for women “at the top of the social pyramid.” As Yang says: “A-class women don’t match with B-class men.”

Why this is a problem: women who have the genes that enable them to do well in business and engineering (e.g. genes for higher IQ, conscientiousness, and drive) are least likely to reproduce. This does not bode well for the gene pool of future humans.

Western countries need more a more pragmatic social science elite that will study and discuss humans as they really are. Ideological feminism and ideological diversity worship are not doing us any favors.

Mrs Kennedy reveals she enjoyed having her husband 'proud of her', saw no reason to have a policy opinion that wasn't the same as his and laughed at the thought of 'violently liberal women' who preferred the more effect Adlai Stevenson to her husband.

She said: 'Jack so obviously demanded from a woman - a relationship between a man and a woman where a man would be the leader and a woman be his wife and look up to him as a man.

'With Adlai you could have another relationship where - you know, he'd sort of be sweet and you could talk, but you wouldn't ever... I always thought women who were scared of sex loved Adlai.'

Men with a preference for 'one-night stands' and negative sexist attitudes towards women are more likely to use aggressive courtship strategies. They compete with other men who are also interested in the woman, tease the woman, and isolate her away from her friends. In response, women with a preference for 'no strings attached' sex and negative attitudes towards other women are more likely to respond to men's aggressive strategies. These findings by Jeffrey Hall and Melanie Canterberry, from the University of Kansas in the US, are published online in Springer's journal Sex Roles.

So more masculinized men and women find each other. I bet both the men and women hooking up this way have higher ring-to-index finger ratios. The "negative attitudes toward other women" is an important clue. I bet these women also have a lower desire to gossip, are taller, and have stronger career ambitions. Do they have less baby fever?

Maria Agthe and her team had 400 students appraise one of four job candidates based on his or her CV, with their photo attached. Although the detailed CVs suggested all the candidates were equally qualified for the job, appearances affected the results. Participants judging a candidate of the opposite sex showed the positive bias you'd expect for highly attractive candidates, being more likely to recommend them for the job. By contrast, participants judging a same-sex candidate showed the opposite pattern, exhibiting a negative bias towards same-sex good lookers. This pattern was mediated partially by the desire for social contact with the candidates - that is, participants were more likely to say they wanted to work with and be friends with opposite-sex beauties, but showed the opposite pattern for good-looking, same-sex candidates. Men and women were similarly prone to negative bias against attractive specimens of their own sex (the effect size was -.5 and -.39, respectively).

But there's a twist: The participants who had the highest self esteem did not discriminate against same sex candidates. What I would like to know: What attributes caused the high self esteem? Good looks? High status background? Personality?

What would also be interesting: Do male and female homosexuals discriminate against same sex or opposite sex beautiful people?

Also, should a company use very high self esteem people to do job interviewing? On the one hand, such people will not discriminate against good looking people of the opposite sex. But will they do a generally better or worse job of choosing employees?

Personnel decisions are crucial to the success of organizations. Yet we do not understand well enough how to make optimal choices.
